When driving at speeds over 75 mph and in cross winds, even a little breeze, I get noise off my side mirrors. There is a notice for the 2019 and 2020 so mine is not covered. And of course, the dealer could not duplicate the noise. They were going to contact Hyundai and see what to do. So now, 2 weeks later, I called Customer Service. Finally told me that someone would call me in less than 10 business days to try to help me out. Two more weeks?? I have several videos with the noise going non stop. Only had the vehicle 3 months and have 9,000+ miles on it. I do a lot of travel for work. Love the vehicle so far but the noise from what I believe is the mirrors is unreal. Anyone else with a 2021 having problems?? Anyone found and cured the problem??
